Debug terminal

[RemcoSmitsDev]

This PR introduces an innovative debugging feature in Zed called the Debug Terminal.

How it works:

When you initiate a debug session, we respond to a runInTerminal reverse request by launching a terminal with specified parameters, including envs and optional args. This allows for direct program execution within the newly opened terminal and allows you to modify any env variables before each time you execute the program that you are trying to debug.

For instance, during a JavaScript debug session, entering node my_program.js prompts the JavaScript debug adapter to automatically attach itself. This seamless integration is possible because the adapter is aware of both the process ID of your active Zed application and the spawned terminal.

Configuration:

Debug terminal for JavaScript

{
  "label": "JavaScript Debug Terminal",
  "command": "JavaScript Debug Terminal",
  "task_type": {
    "type": "debug",
    "kind": "javascript",
    "request": "launch",
    "initialize_args": {
      "console": "integratedTerminal",
      "cwd": "/Users/remcosmits/Documents/code/prettier-test", // This is required for now, later the adapter will insert this.
    }
  }
}
